The spacers are suspended and fastened in the upper reinforcing mesh 2 at the desired distance, that is to say with a corresponding length. Subsequently, casting of the concrete takes place. <IMAGE>

Description

Die Erfindung betrifft einen Betonfußboden nach dem Ober­begriff des Anspruches 1 und ein Verfahren zum Verlegen von Heizungsrohren für einen solchen Betonfußboden.The invention relates to a concrete floor according to the preamble of claim 1 and a method for laying heating pipes for such a concrete floor.

Es ist bekannt, bei derartigen Fußbodenkonstruktionen für einen Betonfußboden, d.h. eine sog. Betonplatte, die Heizungs­rohre unmittelbar angrenzend an die Bewehrungsgitter, d.h. entweder in der unteren oder in der oberen Bewehrungsebene, zu befestigen.It is known in such floor constructions for a concrete floor, i.e. a so-called concrete slab, the heating pipes directly adjacent to the reinforcement mesh, i.e. either in the lower or in the upper reinforcement level.

Durch die EP 0 209 618 ist ein Betonfußboden der eingangs genannten Art bekannt, bei dem die Heizungsrohre an dem oberen Bewehrungsgitter befestigt sind.EP 0 209 618 discloses a concrete floor of the type mentioned at the outset, in which the heating pipes are fastened to the upper reinforcement grid.

Ein Betonfußboden, d.h. eine Betonplatte, wie sie hier mit einer Fußbodenheizung versehen werden soll, unterliegt vielfältigen Spannungen. Diese Spannungen werden durch die Temperatur, ausgehend von der Fußbodenheizung, beeinflußt. Werden beispielsweise die Heizungsrohre in der oberen Be­wehrungsebene angeordnet, so kommt es zu Druckspannungen im oberen Bereich aufgrund des höheren Temperaturniveaus und damit zu einer Ausdehnung, so daß Risse in der Betonplatte auftreten können, die schließlich das Tragverhalten be­einflussen. Entsprechende Probleme treten bei der Anordnung der Heizungsrohre im Bereich des unteren Bewehrungsgitters auf.A concrete floor, ie a concrete slab, as it is to be provided with underfloor heating here, is subject to various tensions. These tensions are caused by the Temperature influenced by the underfloor heating. If, for example, the heating pipes are arranged in the upper reinforcement level, compressive stresses occur in the upper area due to the higher temperature level and thus expansion, so that cracks can occur in the concrete slab, which ultimately influence the load-bearing behavior. Corresponding problems arise with the arrangement of the heating pipes in the area of the lower reinforcement grid.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Beton­fußboden und ein Verfahren der eingangs genannten Art zu schaffen, bei dem optimale Wärmeübergangsbedingungen er­reicht und eine temperaturunabhängige und spannungsfreie Fußbodenkonstruktion unter Beibehaltung hoher Festigkeits­eigenschaften ermöglicht werden.The invention is based on the object of creating a concrete floor and a method of the type mentioned, in which optimal heat transfer conditions are achieved and a temperature-independent and stress-free floor construction is made possible while maintaining high strength properties.

Diese Aufgabe wird bei einem Betonfußboden nach dem Ober­begriff des Anspruches 1 durch das Kennzeichen dieses An­spruches gelöst. Bei einem Verfahren nach Anspruch 2 wird diese Aufgabe durch die Verfahrensschritte nach dem Kenn­zeichen dieses Anspruches gelöst.This object is achieved in a concrete floor according to the preamble of claim 1 by the characterizing part of this claim. In a method according to claim 2, this object is achieved by the method steps according to the characterizing part of this claim.

Bei dem Betonfußboden nach der Erfindung werden die Heizungs­rohre nicht in den Bewehrungsebenen, d.h. angrenzend oder anliegend an die Bewehrungsgitter angeordnet, sondern in der neutralen Ebene zwischen den beiden Bewehrungsebenen. Hier­durch entsteht praktisch eine "eigene Bewehrungsebene". Die Wärmeverteilung erfolgt gleichmäßig und es kommt nicht zu Wärmespannungen und damit zu einer nachteiligen Beeinflussung der Festigkeitseigenschaften. Die Heizungsrohre, die ein sogenanntes Heizungsrohrregister bilden, sind allseitig gleichmäßig im Beton eingebettet und in ihrer Funktionslage nach oben gerichtet. Eine einseitige thermische Belastung eines Bewehrungsgitters erfolgt nicht, so daß auch keine entsprechenden einseitigen mechanischen Belastungen auftreten können.In the concrete flooring according to the invention, the heating pipes are not arranged in the reinforcement planes, ie adjacent or adjacent to the reinforcement grid, but in the neutral plane between the two reinforcement planes. This practically creates an "own reinforcement level". The heat is distributed evenly and there is no thermal stress and thus an adverse influence on the strength properties. The heating pipes, which form a so-called heating pipe register, are embedded uniformly on all sides in the concrete and their functional position is directed upwards. There is no one-sided thermal loading of a reinforcement grid, so that none corresponding one-sided mechanical loads can occur.

Dadurch, daß die Abstandshalter an dem oberen Bewehrungs­gitter fest eingehängt werden, wird auch ein "Aufschwimmen" der Heizungsrohre beim Gießen des Betons verhindert.The fact that the spacers are firmly attached to the upper reinforcement grid also prevents the heating pipes from “floating up” when the concrete is poured.

Im folgenden wird die Erfindung unter Hinweis auf die Zeichnung anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

In der einzigen Figur ist eine Fußbodenkonstruktion schematisch im Querschnitt dargestellt. Auf einer Gründungssohle 10 befindet sich ein Sandabgleich 9, auf den das untere Bewehrungs­gitter 5 mit Hilfe von Abstandsprofilen 12 aufgelegt ist.In the single figure, a floor construction is shown schematically in cross section. On a foundation base 10 there is a sand leveling 9, on which the lower reinforcement grid 5 is placed with the aid of spacer profiles 12.

Auf entsprechend höhere, ebenfalls im Querschnitt gezeigte Abstandskörbe 7, ist das obere Bewehrungsgitter 2 aufgelegt. Eine Verschleißschicht ist mit 1 bezeichnet. Wenn die Fuß­bodenkonstruktion fertiggestellt ist, nehmen die Bauteile die Lage ein, die in der Zeichnung dargestellt ist. Die Heizungsrohre 3 liegen auf gitterförmigen Aufzugsträger­elementen 4, auf denen sie mit Hilfe von Rohrbindern 11 befestigt sind. Die von den Heizungsrohren 3 eingenommene Ebene stellt die neutrale Ebene der Fußbodenkonstruktion dar. Die Aufzugsträgerelemente 4 sind mit Hilfe von Abstands­haltern 6 an dem oberen Bewehrungsgitter 2 aufgehängt und dort befestigt.The upper reinforcement grid 2 is placed on correspondingly higher spacer baskets 7, also shown in cross section. A wear layer is designated by 1. When the floor construction is finished, the components take the position shown in the drawing. The heating pipes 3 lie on lattice-shaped elevator support elements 4, on which they are fastened with the aid of pipe ties 11. The level occupied by the heating pipes 3 represents the neutral level of the floor construction. The elevator support elements 4 are suspended from the upper reinforcement grid 2 by means of spacers 6 and fastened there.

Ein Aufzugsträgerelement 4 liegt zwischen zwei Abstandskörben 7. Der Abstand beträgt bei dieser Konstruktion ca. 1 m.An elevator support element 4 lies between two spacer baskets 7. The spacing in this construction is approximately 1 m.

Der Raum zwischen der Verschleißschicht 1 und dem Sandabgleich 9 wird mit Beton/Estrich ausgefüllt, wenn die Heizungsrohre mit den Aufzugsträgerelementen die dargestellte Lage einnehmen.The space between the wear layer 1 and the sand leveling 9 is filled with concrete / screed when the heating pipes with the elevator support elements occupy the position shown.

Die Montage erfolgt im wesentlichen in folgenden Schritten:The assembly takes place essentially in the following steps:

1. Untere Bewehrungsebene1. Lower reinforcement level

Verlegung der Abstandsprofile 12 mit aufgelegtem Bewehrungs­gitter 5 auf einer Unterkonstruktion, bestehend aus Gründungssohle, Sandabgleich inklusive Trennfolie 8, sowie Verteilung der Abstandskörbe 7 nach einem vorher be­stimmten Raster für die oberen Bewehrungsgitter. Im Bereich von Bewegungsfugen (nicht dargestellt) werden die Bewehrungsgitter unterbrochen, so daß eine Bewegungsfuge von Oberkante bis Unterkante Fertigbeton gewährleistet ist.Laying of the spacer profiles 12 with a reinforcement grid 5 placed on a substructure, consisting of a foundation base, sand leveling including a separating film 8, and distribution of the spacer baskets 7 according to a predetermined grid for the upper reinforcement grid. In the area of movement joints (not shown), the reinforcement grids are interrupted, so that movement joints from the top to the bottom of the precast concrete are guaranteed.

2. Heizebene2nd heating level

Auflegen der Aufzugsträgerelemente 4 zwischen den vorgegebenen Abstandskörben 7 und Verlegen der Heizungsrohre (Rohrregister), mäanderförmig oder bifilar nach vorgegebener Planungsunterlage auf den Aufzugsträgerelementen unter Beachtung der vorgegebenen Bewegungsfugen. Im Bereich der Bewegungsfugen wird das Heizungsrohr durch Rohrschutzhülsen geführt. Die Rohrschutzhülsen haben die Aufgabe, eine zusätzliche Sicherheit gegen mechanische Beanspruchung (Zug-, Druck- und Scherbeanspruchung) im Bewegungsfugenbereich zu bieten. Anschließend erfolgt die Befestigung der Heizungsrohre 3 auf den Aufzugsträgerelementen 4 mittels Rohrbindern 11. Die Abstandshalter 6 in flexiblen Längen werden dann an den Aufzugsträgerelementen befestigt. Die Verteilung der Abstandshalter erfolgt pro laufendem Meter rechts und links sowie in einem Quadratmeter mittig. Eine Positions-Sicherungsklammer 13 wird im unteren Bereich mittig angeordnet, um ein Aufschwimmen der Aufzugsträgerelemente 4 zu verhindern.Place the elevator support elements 4 between the specified spacer baskets 7 and lay the heating pipes (pipe register), meandering or bifilar according to the given planning document on the elevator support elements, taking into account the specified movement gaps. In the area of the expansion joints, the heating pipe is guided through pipe protection sleeves. The tube protection sleeves have the task of providing additional security against mechanical stress (tensile, compressive and shear stress) in the area of movement joints. The heating tubes 3 are then attached to the elevator support elements 4 by means of tube binders 11. The spacers 6 in flexible lengths are then attached to the elevator support elements. The spacers are distributed per meter on the right and left and in one square meter in the middle. A position securing clip 13 is arranged centrally in the lower area in order to prevent the elevator support elements 4 from floating.

3. Obere Bewehrungsebene3. Upper reinforcement level

Auf die Abstandskörbe 7 erfolgt nunmehr die Verlegung der oberen Bewehrungsgitter 2.The upper reinforcement grids 2 are now laid on the spacer baskets 7.

4. Neutrale Zone4. Neutral zone

Mittels der in flexiblen Längen vorliegenden Abstandshalter 6 wird das Aufzugsträgerelement 4 in die neutrale Ebene oder Zone hochgezogen. Dabei werden die Abstandshalter in die oberen Bewehrungsgitter fest eingehakt. Durch einen besonderen Einhakteil des Abstandshalters ist dieser fest mit der oberen Bewehrung verbunden. Durch die Positions-Sicherungsklammer 13 zwischen dem unteren Bewehrungsgitter 5 und dem Aufzugsträgerelement 4 wird ein Aufschwimmen beim Gießen des Betons verhindert.Using the spacers 6, which are available in flexible lengths, the elevator support element 4 is pulled up into the neutral plane or zone. The spacers are firmly hooked into the upper reinforcement grid. The spacer is firmly connected to the upper reinforcement by a special hooking part. The position securing clip 13 between the lower reinforcement grid 5 and the elevator support element 4 prevents floating when the concrete is poured.

Nach erfolgter Montage und nach dem Anheben der Aufzugs­trägerelemente mit den Heizungsrohren wird der Beton/­Estrich vergossen. Es entsteht eine Fußbodenkonstruktion zur Aufnahme von statischen und dynamischen Verkehrs­lasten hoher Qualität. Die Dicke der Fußbodenkonstruk­tion, die Qualität des Betons/Estrichs und die Material­qualität der Bewehrungsebenen sind hierbei maßgebend für die mögliche Verkehrslast. Eine Beeinträchtigung durch die Verlegung der Heizungsrohre erfolgt nicht.After installation and after lifting the elevator support elements with the heating pipes, the concrete / screed is poured. A floor construction is created to accommodate high quality static and dynamic traffic loads. The thickness of the floor construction, the quality of the concrete / screed and the material quality of the reinforcement levels are decisive for the possible traffic load. There is no impairment due to the laying of the heating pipes.
